Depend on latest backbone.browserStorage which has support for IndexedDB
via localforage.
Storage operations are now asynchronous and transactional.
Bugs fixed (mostly by waiting for operations to complete):
* Rooms are now fetched asynchronously, so wait before triggering `show`
or when closing.
* Make sure chat create/update transactions complete before firing events
* Make sure chats and messages have been fetched before creating new ones.
* When doing a `fetch` with `wait: false` on a collection and then
creating a model in that collection, then once the read
operation finishes (after creating the model), the collection is emptied again.
* Patch and wait when saving.
Otherwise we have previously set attributes overriding later ones.
* Make sure api.roomviews.close returns a promise
Test fixes:
* Chats are now asynchronously returned, so we need to use `await`
* Wait for the storage transaction to complete when creating and updating messages
* Wait for all chatboxes to close
Otherwise we get sessionStorage inconsistencies due to the async nature of localforage.
* Wait for room views to close in spec/chatroom.js
In the process, remove the `closeAllChatBoxes` override in
converse-controlbox by letting the `close` method decide whether it
should be closed or not.
- Increase z-index for chatbox flyouts so that they appear above the controlbox
- Also fix a margin offset bug for the controlbox (in smaller viewports)
in which you can set user affiliations and roles.
Also, let getAffiliationList return an Error instead of `null` if you're
not allowed to fetch a particular affiliation list.
It's unlikely that `keepalive` needs to be set to `false`, but there are
some edge cases where it might be useful.
Here's a breakdown of the different configurations of `keepalive` and `auto_join`:
---
* auto_login: false, keepalive: true
This is the default config. Users need to log in manually, but then
Converse will try to reconnect them when the page reloads.
* auto_login: true, keepalive: true
Also very popular configuration. Used with `credentials_url` or `prebind_url`.
* auto_login = `true`, keepalive = `false`
Not sure what this could be useful for. No currently known application.
* auto_login = `false`, keepalive = `false`
Useful when you want some kind of specific action to trigger login, but
you don't want to maintain that state across page reloads.
Also relevant when using a websocket connection with anonymous login.
With websocket it's impossible to maintain anonymous sessions across page
reload because the the session gets removed server-side as soon as the
websocket connection drops and the server won't accept a full JID with
password for an anonymous connection anyway (which could happen upon
page reload when Converse tries to login in again if `keepalive` was `true`).
This change reverts the significant part of 1dfdb36d20
I can't say that I understand why libsignal throws `Error: Invalid signature`
when you try to build a session for your own (sending) device, but given that
messages can only be decrypted once, I guess it isn't really necessary
to encrypt for your own device, since you already have the plaintext.
In addition I've added some error handling so that we can recover
gracefully when session building fails for a subset of devices.
In some cases, it might be desirable to clear cached chat messages once you've
reconnected to the XMPP server.
For example, if you want to prevent the chat history from getting too long or
if you want to avoid gaps in the chat history (for example due to MAM not
returning all messages since the last cached message).
If you're using OMEMO, then you probably don't want to set this setting to
``true``. OMEMO messages can be decrypted only once, so if they then
subsequently get cleared, you won't get the plaintext back.
